Most cold email fails for the same handful of reasons: it is too long, too generic, too pushy, or sent from a domain that is already burned. Here are nine rules that fix that, in order of impact.
- Research before you write. The first line should prove you looked at the company, not that you found their email.
- Keep it short. If it takes more than fifteen seconds to read, it is too long. Aim for a few sentences.
- Make one clear ask. One email, one purpose. A short call, a quick reply, one question. Not three.
- Write like a person. No jargon, no “I hope this email finds you well,” no walls of text. Sound like a colleague, not a brochure.
- Send one-to-one. A message that reads like it was written for one person beats a blast every time, and it protects your domain.
- Pace your sends. Inside working hours, a few minutes apart. Human rhythm, not machine-gun.
- Follow up patiently. No reply is not a no. Wait a sensible interval, then send one polite nudge - and stop the moment they reply.
- Read the reply properly. “Not right now” is a follow-up later. “Not interested” is a permanent stop. Getting this right is most of the job.
- Know when to stop. One opt-out means never again. Respecting that is not just good manners; it is what keeps you deliverable and legal.
None of these are tricks. They are what a thoughtful salesperson already does - just applied consistently, at the top of the funnel, on every single send. That consistency is exactly what an AI SDR is for.
